One inherent weakness of the model has been the need for estimates of the mean number of times a program would cycle around its loop structures and estimates of branching probabilities. Extensive improvements were made in the model on the assumption that good estimates would be inserted during a manual transformation of a given program into a computer processable graph representation. The combination of improved tools for measurement of program activities and recently developed analysis programs now permit automatic analysis of source programs. The automatic analysis is based on more reliable measured a priori statistics. This paper discusses a valuable by-product of this measurement and analysis which directs attention toward those parts of a program which are leading candidates for application of optimization techniques. In particular we present an example of the automatic analysis of programs written in the FORTRAN IV language. FORTRAN was selected as a first target for analysis because there exists a large number of time-consuming programs written entirely in FORTRAN.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122638502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hoped to realize four significant advantages from such a move:\u0000 1. A small computer---being programmable---offered the opportunity of increased flexibility in the control of remote terminals.\u0000 2. The prices of small computers had decreased to the point that it seemed reasonable to expect such a system to cost less than the IBM 2702.\u0000 3. Since IBM required that each TTY line be connected to the 2702 via a 3233 line adapter and a 103A or 103F data set, we felt that significant savings might be obtained through lower incremental costs per line, achieved by providing either direct TTY connection or the use of lower cost data sets on leased private lines.\u0000 4. By handling as many communication problems as possible in the small computer, we hoped to reduce substantially the amount and complexity of system modifications in the large computer.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124757432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, I do believe that the principles are fundamental in that predictability can be guaranteed to increase if they are followed.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126227343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Process control oriented programming languages provide a control engineer with means to learn and hence set up, modify, and operate a control system with ease. They eliminate the complication of involving a programmer, who generally has little knowledge about process control engineering. The result is a reduction in time and dollars for digital control system generation.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128733212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas a static image (such as a Picasso or a complex graph) may convey complex information through a single picture, animation conveys equivalently complex information through a sequence of images seen in time. It is characteristic of this medium, as opposed to static imagery, that the actual graphical information at any given instant is relatively slight. The source of information for the viewer of animation is implicit in picture change: change in relative position, shape, and dynamics.

The common element essential to such mobility is the establishment of standards for programs, programmers, and documentation. The adoption of high-level programming languages such as COBOL, FORTRAN, ALGOL, and JOVIAL is a required element of such standards. The high-level languages are innately self-documenting---an essential for transferability. Thus, their use provides assistance in the transfer of programs among activities; the conversion from one computer generation to another; the conversion from one computer manufacturer to another; and the transfer of programs for back-up and readiness.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130008456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another author considered GO to be somewhat mysterious, making it a challenge to those interested in automating it. Apparently the game was described as being mysterious to indicate that people were able to play it without knowing how they were able to play so well. More study of this complex game may reward us with new insight into human perceptual and problem solving abilities as well as foster the development of new techniques for artificial intelligence. This report describes a program which plays GO. The program uses an information processing model to produce perceptual features which are seen by human GO players, and is capable of several responses to the recognition of significant configurations of these perceptual features.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122263564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
